Bell’s palsy is the most common cause of facial paralysis. It usually affects just one side of the face. Symptoms appear suddenly and are at their worst about 48 hours after they start. They can range from mild to severe and include:
Twitching
Weakness
Paralysis
Drooping eyelid or corner of mouth
Drooling
Dry eye or mouth
Excessive tearing in the eye
Impaired ability to taste
Scientists think that a viral infection makes the facial nerve swell or become inflamed. You are most likely to get Bell’s palsy if you are pregnant, diabetic or sick with a cold or flu.
Three out of four patients improve without treatment. With or without treatment, most people begin to get better within 2 weeks and recover completely within 3 to 6 months.
